BACKGROUND OF THE INVENTION

[0001] The present invention relates generally to clamping apparatus and feeding stock material on a wood shaper, a router table and a table saw, particularly to normal cutting, shaping and precision processing of material on a wood shaper, a router table and a table saw, and specifically to climb cutting, shaping and the precision processing of stock material and in the form of small pre cut panels.

[0002] The use of fingers, finger boards, hold down devices, power feeders, fences and a miter slot accommodating miter gages, sliding miter jigs and other accessories milled in the stock support tables of wood shapers, router tables and table saws is representative of the prior art that has addressed apparatus associated with the processing of materials. The invention described does not solve the problem of high precision processing of stock material and small work pieces of material with accuracy, safety, speed and consistent results.

[0003] These systems and methods allow for the manufacture of medium size work pieces only, in a cumbersome manner, while the operator contends with the issue of clogging. Cut material debris in a recessed miter slot may result in the loss of precision and hazard to the operator.

[0004] There is no system, which currently exists that can easily be converted to process small work pieces with great precision, flexibility of positioning and offer operator ease and safety.

[0005] Existing systems do not produce precision consistent results, efficient use of the operators time or reduce operator stress. Kick back, potential for injury, is not reduced.

[0006] There is no system that eliminates saw marks and chatter, the use of waxes, chipping, splitting, tear and blow out of the work piece.

[0007] These systems do not dimension the wood as well as form it. Slightly over cut material is not accommodated. Existing systems do not have a unique indexing system that uses spacers or interfaces with other manufacturers gages for precision processing of materials.

[0008] Many systems do not eliminate waste and improve the performance of the machine on which it is installed.

[0009] These systems require a number of light passes to be made. The best feed rate is the slowest speed.

[0010] From the above, it can be seen what is needed is a system and a process for installation of it's major components, comprised of a clamping apparatus and adjustable back fence, for the precision processing of work pieces on a wood shaper, router table and table saw with a greater degree of operator ease, speed, safety, more economical and consistent results, as a clamping apparatus and back fence assembly.

DETAILED DESCRIPTION OF THE INVENTION

[0069]FIG. 1 is a perspective view of the clamping apparatus assembly 10. It is comprised of a platform base 12 made from 0.75 inch thick Mic 6 aluminum plate. The platform base 12 has a top 14, a bottom 16, a front 18, a back 20, a left side 22 and a right side 24. The top 12 has mounted to it a material stop 52 held in place by general assembly round head machine screws 40. Adjacent to the material stop 52 on the top surface 14 is applied a non slip surface film 48 such as 3M Brand Safetywalk 3-10 Medium Resilient Tread Film. The bottom 16 of platform base 12 has applied to it a slip surface film 50 such as Woodcraft Brand UHMW Slick Strip.

[0070] A overhead guide/guard 26 is made from clear poly carbonate sheet such as GE Brand Lexan. Oversized fastening holes are drilled to accommodate general assembly round head bolts 40 which fixes the overhead guard guide 26 to guide/guard risers 28. This is done to accommodate final squaring and alignment with a processing machine fence guide 98. Guide/guard risers are affixed to the top of platform base 12 by general assembly flat head machine screws 42 inserted through the bottom 16 of platform base 12.

[0071] A secondary riser support 57 is mounted to the platform base 12 with general assembly flat head machine screws 42 to support secondary handle 56.

[0072] Four clamp risers 46 are mounted to platform base 12 by general assembly flat head screws 42. This is done to raise sacrifice stick clamp 44, such as De Sta Co Brand #309U, to appropriate height. Sacrifice stick 60 is held in its place by sacrifice stick clamp 44. The purpose of sacrifice stick 60 is to block in the work piece 58. This serves two purposes. One is to hold in place one side of the work piece 58. The second is to absorb pressure from any cutter it may encounter, such as wood shaper cutter 88, router cutter 90 and table saw blade 92. The work piece 58 is thus saved from break out and chipping by sacrifice stick 60.

[0073] The work piece is held in place by large clamp 30 such as De Sta Co Brand #245U. The large clamp 30 is modified by the addition of a custom primary handle 54. The large clamp 30 is mounted on large clamp riser block 32 by four screws 40. Clamp riser block 32 is made from 0.75 inch thick 6061 aluminum plate and has four drilled and tapped holes in its upper surface to accommodate four screws 40. A critical feature of large clamp block 32 is an approximately centrally located drilled and tapped hole in it's bottom surface. This drilled and tapped hole accommodates clamp riser block flat head machine screw 38 which is a 0.5 inch×13×1.5 inch in size. This is a critical part of the assembly as the center line of screw 38 becomes the central pivot access of the entire component assembly, comprised of clamp 30, block 32, four screws 40 and the screw 38. This entire assembly may be placed in any of the plurality of holes 100 drilled through platform base 12. The adjustment holes for block 100 are reamed to accommodate a plane surface 38 a, which is the underside of the head of clamp riser block screw 38. Another key feature of the invention is, once clamp 30 is pivoted into it's selected position, screw 38 is tightened to bear on surface 38 a. An amount of surface area 38 a is needed to supply the critical binding force to secure and hold the placement of the components mentioned above.

[0074] Another key feature of the invention is work piece block 62 which is comprised of ten plane surfaces, as shown in the drawings in the preferred embodiment, cut from UHMW Polypropylene (ultra high molecular weight) sheet material. A work block non slip top film 64 and a work block non slip bottom film 66 is applied respectively to work piece block 62. Block 62 may have six or more surfaces, in various manufactures and accommodating various shaped work pieces 58. Blocking of the work piece 58 can be accomplished by contact of block 62 on one, or two sides in the preferred embodiment, of the work piece 58. In particular the block 62 or the work piece 58, as chosen by the operator, is held in it's place by medium clamp 34 such as DeSta Co Brand #237U, which is mounted at the opposite end of the clamping apparatus 10 respective to clamp 30.

[0075] The medium clamp 34 is mounted on medium clamp riser block 36 by four screws 40. Block 36 is made from 0.75 inch thick 6061 aluminum plate and has four drilled and tapped holes in its upper surface to accommodate four screws 40. A critical feature of block 36 is an approximately centrally located drilled and tapped hole in it's bottom surface. This drilled and tapped hole accommodates screw 38 which is a 0.5 inch×13×1.5 inch in size. This is a critical part of the assembly as the center line of screw 38 becomes the central pivot access of the entire component assembly, comprised of clamp 34, block 36, screws 40 and the screw 38. This entire assembly may be placed in any of the plurality of holes 100 drilled through platform base 12. The adjustment holes 100 are reamed to accommodate a plane surface 38 a, which is the underside of screw 38. This is another key feature of the invention, as once clamp 34 is pivoted into it's selected position, screw 38 is tightened to bear on surface 38 a. This amount of surface area 38 a is needed to supply the critical binding force to secure and hold the placement of the components mentioned above.

[0076]FIG. 2 is a plan view of the clamping apparatus of FIG. 1 and further shows the assembly configuration as described above.

[0077]FIG. 3 is perspective view of a first embodiment assembly of the clamping apparatus of FIG. 1. This embodiment is smaller in it's dimension and can also be made of lighter materials than are specified. The object of this first embodiment is to accommodate small processing machines such as are more commonly used by the amateur wood worker in a home environment FIG. 3 is a perspective view of the clamping apparatus assembly 10′. It is comprised of a platform base 12′ made from 0.75 inch thick Mic 6 aluminum plate. The platform base 12′ has a top 14′ a bottom 16′, a front 18′, a back 20′, a left side 22′ and a right side 24′. The top 12′ has mounted to it a material stop 52′ held in place by general assembly round head machine screws 40′. Adjacent to the material stop 52′ on the top surface 14′ is applied a non slip surface film 48′ such as 3M Brand Safetywalk 3-10 Medium Resilient Tread Film. The bottom 16′ of platform base 12′ has applied to it a slip surface film 50′ such as Woodcraft Brand UHMW Slick Strip.

[0078] A overhead guide/guard 26′ is made from clear poly carbonate sheet such as GE Brand Lexan. Oversized-fastening holes are drilled to accommodate general assembly round head bolts 40′ which fixes the overhead guard guide 26′ to guide/guard risers 28′. This is done to accommodate-final-squaring and alignment with a processing machine fence guide 98′. Guide/guard risers are affixed to the top of platform base 12′ by general assembly flat head machine screws 42′ inserted through-the-bottom 16′ of platform base 12′.

[0079] In this-first embodiment primary-handle riser supports 55′ extend to a distance above large clamp 30′ and affixed to them is a primary handle 54′.

[0080] A secondary riser support 57′ is mounted to the platform base 12′ with screws 42′ to support secondary handle 56′.

[0081] Four clamp risers 46′ are mounted to platform base 12′ by screws 42′. This is done to raise sacrifice stick clamp 44′, such as De Sta Go Brand #309U to appropriate height Sacrifice stick 60′ is held in its place by clamp 44′. The purpose of sacrifice stick 60′ is to block in the work piece 58′. This serves two purposes. One is to hold in place, one side of the work piece 58′. The second is to absorb pressure from any cutter it may encounter, such as wood shaper cutter 88′, router cutter 90′ and table saw blade 92′. The work piece 58′ is thus saved from break out and chipping by sacrifice stick 60′.

[0082] The work piece is held in place by large clamp 30′ such as De Sta Co Brand #245U. The large clamp 30′ is mounted on large clamp riser block 32′ by four screws 40′. Clamp riser block 32′ is made from 0.75inch thick 6061 aluminum plate and has four drilled and tapped holes in its upper surface to accommodate four screws 40′. A critical feature of block 32′ is an approximately centrally located drilled and tapped hole in it's bottom surface. This drilled and tapped hole accommodates clamp riser block flat head machine screw 38′which is a 0.5 inch×13×1.5 inch in size. This is a critical part of the assembly as the center line of screw 38′ becomes the central pivot access of the entire component assembly, comprised of clamp 30′, block 32′, four screws 40′ and the screw 38′. This entire assembly may be placed in any of the plurality of holes 100′ drilled through platform base 12′. The holes 100′ are reamed to accommodate a plane surface 38 a′, which is the underside of screw 38′. This is another key feature of the invention, as once clamp 30′ is pivoted into it's selected position, screw 38′ is tightened to bear on surface 38 a′. This amount of surface area 38 a′ is needed to supply the critical binding force to secure and hold the placement of the components mentioned above.

[0083] Another key feature of the invention is work piece block 62′ which is comprised of ten plane surfaces, as shown in the drawings in the preferred embodiment, cut from UHMW Polypropylene (ultra high molecular weight) sheet material. A work block non slip top film 64′ and a work block non slip bottom film 66′ is applied respectively to work piece block 62′. Block 62′ may have six or more surfaces, in various manufactures and accommodating various shaped work pieces 58′. Blocking of the work piece 58 can be accomplished by contact of work piece block 62′ on one, or two sides in the preferred embodiment, of the work piece 58′. In particular the block 62 or the work piece 58′ is held in it's place by medium clamp 34‘such as DeSta Co Brand #237U; which is mounted at the opposite end of the clamping apparatus 10′ respective to clamp 30′.

[0084] The clamp 34′is mounted on medium clamp riser block 36′ by four screws 40′. Block 36′ is made from 0.75 inch thick 6061 aluminum plate and has four drilled and tapped holes in its upper surface to accommodate four screws 40′. A critical feature of block 36′ is an approximately centrally located drilled and tapped hole in it's bottom surface. This drilled and tapped hole accommodates clamp riser block flat head machine screw 38′ which is a 0.5inch×13×1.5 inch in size. This is a critical part of the assembly as the center line of screw 38′ becomes, the central pivot access of the entire component assembly, comprised of clamp 34′, block 36′, four screws 40′ and screw 38′. This entire assembly may be placed in any of the plurality of holes 100′ drilled through platform base 12′. The holes 100′ are reamed to accommodate a plane surface 38 a′, which is the underside of screw 38′. This is another key feature of the invention, as once clamp 34′ is pivoted into it's selected position, screw 38′ is tightened to bear on surface 38 a′. This amount of surface area 38 a′ is needed to supply the critical binding, force to secure and hold the placement of the components mentioned above.

[0108]FIG. 25 is a sectional view of an indexing block.

[0109]FIG. 26 is a sectional view of a guide attachment component.

[0110]FIG. 27 is a sectional view of a adjustable indexing component. T extrusion 122 has a vinyl strip 164 attached by adhesive to it's top surface. The purpose of the vinyl strip 164 is to provide an eraceable marking surface. Indexing marks are placed on this vinyl strip 164 by the operator for his convenience and memory in setting up the system assembly 110. It is common that cutters or cutter sets are changed during a manufacturing run. Correspondence must be maintained. Work piece 58 is precessioned and processed by this method.

[0111]FIG. 28 is a partial sectional view of the adjustable back fence 112 as it typically connects with the indexing system 116 of the assembly and it's components. This view further shows what has already been described in the preferred embodiment.

[0112]FIG. 29 is a partial view of the assembly with the front and back fence portions shown in phantom lines. This view further shows what has already been described in the preferred embodiment. This view more fully shows the use and configuration of spacer 160 and back stop 162.

[0113] Spacers 160 are an integral part of the system assembly 110. Spacers 160 limit the movement of horizontal plate 114 toward the wood shaper cutter 88 until the spacer 160 is stopped by the back stop 162. Back stop 162 is adjustable and moves in either direction in extrusion 120. Back stop 162 is fixable by adjustment and tightening of it's knob 134. To more fully describe spacers 160. Spacers 160 can be used singularly or in pairs and can be any length from 0 to infinity. Typically spacers 160 are provided in lengths from 1.5 to 2.5 inches in increments of 0.0625 of an inch. Spacers 160 can be combined with other spacers 160 of integer dimensions. Spacers 160 can be of adjustable length.

[0114] Spacers 160 functionally provide memory. Spacers 160 provide a means for the operator to quickly change adjustment of system assembly 110.

[0115]FIG. 30 Shows an embodiment of spacer 160 which is of adjustable length by rotation of the hex bolt 166.

[0116]FIG. 31 Shows a further embodiment of spacer 160 which is comprised of three precision finger gauges 168 measuring 0.25 inches and three precision finger gauges 170 measuring 0.0625 in thickness. Gauges 168 and 170 pivot on center about a connecting bolt 172. Plates 174 functionally align with holding block 176 which also pivots about a connecting bolt 172.

[0117] Set ups from 0.0625 inch to 0.9375 inch can immediately be obtained from use of various combinations of the gauges 168 and 170.

[0118] By setting up one side of the indexing channel system 116 with a spacer setting 0.0625 inch less than the other side, the middle of the horizontal plate 114 will be moved 0.03125 inch and will functionally dimension to this small tolerance.

[0119]FIG. 32 Shows, in use, embodiment of spacer 160 as described in FIG. 31.

[0120] In conclusion thus, the reader will see the Positioning System For Work Piece Milling and a process for installation of it's major components, comprised of a clamping devise and adjustable back fence, for precision processing of material on a wood shaper, a router table and a table saw provides a highly reliable, light weight, yet heavy duty, economical device that can be used in a manual version by professionals and amateurs alike and can also be automated by any means possible to further enhance it's efficiency. In fact great value is obtained from being able to stack and interchange a clamping apparatus 10, 10′ and a adjustable back fence assembly 112 to convert from cope cuts to pattern cuts. Great advantage is obtained in being able to switch easily between doing the cope and pattern cuts. This is done by mounting an entire set of cutters, typically six stacked onto the shaper spindle, all at the same time. Individual cutters are typically 1.250 inches in thickness. The cope clamping device has a base that is typically 1.290 inches in thickness. The work piece is mounted on this base. This allows for precision positioning of the work piece to perform the cope cut on the top cutters. The pattern cut is obtained by use of the back fence and the shaper table surface to engage the bottom cutters. With this system, once the cutters are installed, there is no need to move or adjust the cutters. Precision join able cope and pattern cuts are obtained by use of this system.

[0121] While the above description contains many specificties, these should not be construed as limitations on the scope of the invention, but rather as an exemplification of one preferred embodiment and a first embodiment thereof. Many other variations are possible such as additional numbers of clamps plates, extrusions, automation, other proportional and dimensional configurations, various use of materials in construction, pluralities of work piece blocks, handles and knobs and installation on all types of processing equipment.

[0122] Accordingly, the scope of the invention should be determined not by the embodiments illustrated, but by the appended claims and their legal equivalents.
